Umpqua River Bridge Replacement

Scope

Michels completed the construction of large drilled shafts for the replacement of the Umpqua River Bridge. The existing bridge is more than 90 years old and is being replaced to accommodate modern traffic, providing a wider roadway and adjusting the tight corners at both ends of the bridge.

The crew installed 12 8-foot diameter drilled shafts with 16-foot rock sockets in 15,000psi sandstone for the six bridge piers, 57 soldier piles embedded in rock, 63 permanent ground anchors, and 6,000 square feet of timber lagging. Bridge construction is scheduled for completion in spring 2022.
